“…A larger frequency range (>24GHz) is necessary for the exceptionally fast data transfer speeds of 5G and later communications [23]. The designed antenna sensor operates in the higher frequency band (>32 GHz) which is very high compared to some recent works [24]- [26].…”

Breast cancer is one of the deadliest forms of disease that affects women worldwide. X-ray mammography, magnetic resonance imaging, and ultrasound are all helpful methods of medical imaging, but they have their own limitations due to low tissue contrast and side effects. Millimeter wave (mmWave) imaging has been offered as a viable alternative to the conventional screening methods due to their drawbacks. Without exposing the patient to ionizing radiations, malignant lesions can be detected by using the dielectric discontinuities in the tissues. The purpose of this work is to develop a simple, low-cost miniaturized mmWave imaging antenna sensor that can be used to detection of breast tumors or cancers in women by monitoring the changes in the antenna's S11 parameter. The dimension of the proposed rectangular mmWave antenna is 5 mm × 5 mm × 0.578 mm. The proposed antenna sensor has an operating frequency band range of 32.626 GHz to 33.96 GHz with a peak gain of 6.65 dB and an efficiency of 91.46% in terms of radiation which makes it a suitable system for fifth generation (5G) communication. As well as the antenna sensor can detect very tiny malignant that size ≥1 mm inside the breast fantom.

“…Instead of adding a director to the Vivaldi antenna, its slot is doubled (DSVA) to enhance the BW and directivity [5,6]. For UWB, target detection, and high-speed 5G communication applications, BW and impedance matching improvement are achieved by etching slots on the proposed DSVAs' edges in [5,7,8]. Enhanced directivity and gain required for UWB imaging and radar systems are achieved in the proposed DSVAs in [9,10] by adding zero-index metamaterial (ZIM) unit cells and a parasitic element, respectively.…”

In this study, at ultra-wideband (UWB) frequency band (3.1–10.6 GHz), we propose the use of compact 2:1 and 3:1 nonuniform transmission line Wilkinson power dividers (NTL WPDs) as feeding networks for simple 2 × 1 linear UWB Vivaldi tapered and nonuniform slot antenna (VTSA and VNSA) arrays. The 2:1 and 3:1 tapered transmission line (TTL) WPDs are designed and tested in this work as benchmarks for NTL WPDs. The VTSA array provides measured S11 < −10.28 dB at 2.42–11.52 GHz, with a maximum gain of 8.61 dBi, which is 24.39% higher than the single element. Using the VNSA array, we achieve 52% compactness and 6.76% bandwidth enhancement, with good measured results of S11 < −10.2 dB at 3.24–13 GHz and 15.11% improved gain (8.14 dBi) compared to the VNSA single element. The findings show that the NTL and Vivaldi nonuniform slot profile antenna (VNSPA) theories are successful at reducing the size of the UWB WPD and VTSA without sacrificing performance. They also emphasize the Vivaldi antenna’s compatibility with other circuits. These compact arrays are ideal for high-resolution medical applications like breast cancer detection (BCD) because of their high gain, wide bandwidth, directive stable radiation patterns, and low specific absorption rate (SAR). A simple BCD simulation scenario is addressed in this work. Detailed parametric studies are performed on the two arrays for impedance-matching enhancement. The computer simulation technology (CST) software is used for the simulation. Hardware measurement results prove the validity of the proposed arrays.

“…Nevertheless, this research not mentioning the substrate used. Multiple strips of Vivaldi antenna for high-speed 5G communication also had been studied [14], this study is limited on the use of double slotted with few corrugations and grating elements.…”

This paper introduces a millimetre-wave antenna design for 5G application using an alternative substrate called Kevlar-Alumina Composite. Kevlar-Alumina Composite had been researched and measured comprehensively by Indonesian Institute of Science (LIPI) Bandung showing dielectric value of 9.2. The application of the antenna geometry is based on Vivaldi Coplanar antenna with L shaped feeding on the ground plane. Vivaldi Antenna is chosen as it has a relatively small size with various structures. An antenna of 3.75 GHz for 5G application using Kevlar-Alumina Composite is proposed. The simulated results of single-element 5G antenna have return loss value of -21.949 dB, 1.173 VSWR, directive radiation pattern at E-Plane and H-plane, and surface current. The use of the Kevlar-Alumina Composite performed good results.
